I now have the Kindle Android app running on my PRS-T1, and I got it from the Amazon Appstore. The app turns the page a little slower than my K4, but it does run. I’ve sent several ebooks to the T1 and I even downloaded a library book. The T1′s page turn buttons don’t work with the Kindle app, but the rest of the app works just like it should (bookmarks, highlights, etc).
